CREE-K. MICHIGAN, .A COR-IORATION OFMICI-II' REGISTER-DAMPER-OPERATINGDEVICE;

Application filed December 10, 1924. Serial at. 755,356.

To all whom it may concern.

Be it known that I. Vnmrui T. TRUAX,

ters, and concerns the devices for swinging the damper or gate towardsand from the grating or open-work front of the register, according as itis desired to shut off the warm air from the room or direct it into theroom through the front grating;

The object of this invention is to provide a lever device and relatedmemberseach of special construction and arrangement with respect toanother, whereby the register damper may be held open or closed or inany intermediate position by a spring clasp, which permits the changingof the inclination of the damper when desired easily and without theexertion of other than a light pressure of the fingers. It is further anobjeot of this invention to produce a contriv ance of the nature stat-edthat will enable the various parts in the process of manufacturing to beconveniently and quickly assemblcd or erected, in order that the totalcost of production in commercial quantities may be reduced as far. aspracticable.

In the accompanying drawings the special construction and preferredarrangement of the parts of this invention are illustrated. Fig. 1represents a front view of a register to which this invention isapplied, and shows the position of the finger piece of the operatinglever in the register front. 2 is a rear view, showing the parts insidethe regis ter front or frame. Fig. 8 is a side view. Fig. 4; is avertical section on the broken line l4 of Fig. 2, the parts drawnbeingshown full size to render the illustration clearer. Fig. 5 is a frontview of a portion at the middle of the flanged stiffening piece arrangedhorizontally on the inside of the register front, and shows theprojecting portion of the flange, with the downwardly extending rigidpart, and the spring attached to the projecting member and arrangedadjacent to the rigid portion. Fig.

6 is a top view of the middle portion of thespring is omitted. F 7. is avertical section of the register front on thesame line as,

stated for Fig. 4, but showing the damper open, and the position oftheoperating lever then assumed. In ithose parts are representedin thepositions reached when the damper is closed, that is to say, noved tocover the opening in the register front over which the grating extends.Fig; 8 is a vertical section of the registerfront taken on thebrokenline 8-8 of Fig. 2.

Throughout the drawings and description the same letter is used to referto the same part. 7 i r Considering the drawings, the front A of theregister, has the usual opening for the passage outward of the warm air,covered by the grating or openwork 0a. The finger piece ofthe operatinglever B is shown projecting before the front A, and movable in theslot bin the front through which the lever passes.

On the inside of the front A is the damper Cfand along its upper edgethe damper,

has the usual rounded and wired termination Asbest shown in Figs. 4 and7, the operatlng lever B has a rounded recess'D,

which takes inthe rounded and pivoted upper edge of the damper. It maybe stated herethat the recess engages the rounded edge 0, which is thefulcrum ofthe lever B. The lower en-dcl of the lever is pointed orwedge-shaped and is passed through the damper C as illustrated to securethe end i to the damper.

Besides the finger piece or portion which passes through the front A asshown, the

lever B has an extended flat portion E in-y tersectedby a straight upperedge resulting in a corner or angle a. It will be noted in Figs. 2, iand 7, that the fiat extension E' of the body of the lever B is claspedbetween the flat spring 13 and therigid downwardly extending portion 7of a projection G of the flanged member 7; The. extension E, as will ibe understood, is always in the frictional t grasp of the spring clasp,and is thereby yieldingly held in any position either open or closed orintermediate. described Zrelatingto the spring clasp and The parts just,

to the flanged member 9 are also shown in Figs. 5 and 6.

The flanged member 9 is a stiffening piece or bar, and as shown in Fig.2, and in Fig. 8, extends horizontally upon the inside of the. front Ajust above the grated opening. It is usually attached to the front byrivets or spot welding. In practice, side stifiening strips H and h areattached vertically on the inside of the front A, as shown in Fig. 2.

To support or hang the damper G movably, as shown in Figs. 2, 4t, 7 and8, the web of the flanged member 9 is extended downwardly to form thehangersJ, which encircle the rounded edge 0 of the damper at usually twopoints as illustrated, thereby supporting the damper pivotally upon andWithin the front A. This invention is not limited to the particulardevices set forth for pivotally holding the rounded upper edge of thedamper, as that arrangement is readily modified.

The above description is the same in all respects as the description setforth in the abandoned application for the same inven tion filed April28, 1921, Serial Number assess.

In the ope 'ation of this invention, it will be understood as alreadyexplained that the -frictional grasp of the spring F and the rigidportion 7 of the projecting part of the flanged member 9 is constant,and will hold the damper at any point. But little effort upon the fingerpiece'of the lever B is called for to move the damper. Wlhen the air isto be shut oil from the room, the damper is moved to cover the gratingor openwork a of the front, and the closing movement is limited bycontact with the front. lVhen the warm air is tobe directed into theroom through the grating a, the damper is swung into the positionillustrated in Flg. 7, and it will be noted that the opening movementwill be brought to a stop when the corner 6 of the flat extension E ofthe lever B strikes the projection G of the flange of the mem ber 9.Furthermore, it will be noted that, for convenience and rapidity ofassembling in the process of manufacture, the lever and damper may beassembled and placed in position, and the hangers J bent about therounded edge 0 of the damper With practical-1y a minimum of labor andtime.

Having now described this invention and explained'the mode of itsoperation, what I claim is i 1. In a register damper operating device,the combination With a register front, of a projecting member attachedto the front inside thereof, the said projecting member having a rigidportion extending downwardly, a spring attached to the projecting memberand arranged facing the said rigid portion, a damper having an upperedge pivotally supported by the" said front, :1

lever having a recess engaging the said upper edge of the damper as afulcrum, the said lever having a finger piece passing through the frontand an extension inside of the front arranged between the said springand the rigid portion of the projecting member and in frictional contactwith them, and the said lever having an end secured to the said damper.
